Using 334-nm light, we demonstrate side writing of Bragg gratings with an index change of ~10(-4) in germanium-doped fibers. No hydrogen loading of the fibers was required. These gratings have the… (More)

We propose that a composite hydrophobic SAM film with 100% coverage of all exposed surfaces can be used in many advance packaging applications. For example, a SAM moisture barrier with conventional… (More)
